Re: How can I derive a dependency filename from a stem value?

Hi Noel,


>I believe this is in the documentation.  See, for example, the Automatic Variables section in >make-info.6.

It looks like I can not use automatic variables in the prerequisite lines?
I tried things like:

 %ddb/generic.db : %cmd/dc_setup.tcl \
                   %cmd/$(filter_out $*,../../ work)_constr.tcl
                        
But this is not filled in.
also a line like:
                   %cmd/$*_constr.tcl

is not filled in.
Do you (or somene else) have a suggestion?

Thanks

Hans Peter.
